Transport your Wilderness Systems kayak with strength and ease on the Heavy Duty Kayak Kart. Large 12” diameter airless wheels never go flat and roll over rough terrain smoothly. This cart supports kayaks up to 450 lbs. with its bunker bar frame. The Heavy Duty Kayak Kart can be adjusted widthwise and has two adjustable height options. No scupper posts to prevent boat damage. Two security straps are included and it is easy to load and unload your kayak with no kickstand required. The Kart is also collapsible and storable within Oval Orbix hatches and is constructed of marine-grade, high-strength, heat-treated aluminum alloy for superior strength.
